Introduction

This white paper provides an overview of the recent project for migrating workloads from Amazon Web Services (AWS) to Oracle Cloud Infrastructure (OCI). The migration includes transitioning from Amazon Elastic Kubernetes Service (EKS) to Oracle Kubernetes Engine (OKE) and migrating data from Amazon S3 to Oracle Cloud Object Storage.

Project Overview

  • Project Name: AWS to Oracle Migration
  • Duration: 3 Months
  • Team: DevOps Engineers, Cloud Architects, Database Administrators

Objectives

  • Seamlessly migrate Kubernetes workloads from AWS EKS to Oracle OKE
  • Transition object storage from AWS S3 to Oracle Cloud Object Storage
  • Minimize downtime and ensure data integrity during migration
  • Optimize costs and improve performance on the Oracle Cloud platform by 35 to 40% PA

Migration Steps

1. Pre-Migration Planning
  • Assess current AWS infrastructure and workloads
  • Define migration strategy and success criteria
  • Set up Oracle Cloud account and configure necessary services
  • Train team on Oracle Cloud tools and best practices
2. Migrating EKS to OKE
  • Export current Kubernetes configurations from AWS EKS
  • Set up Oracle Kubernetes Engine (OKE) clusters
  • Import and apply Kubernetes configurations to OKE
  • Test workloads in OKE environment to ensure functionality
3. Migrating S3 to Oracle Cloud Object Storage
  • Inventory and categorize data stored in AWS S3
  • Set up Oracle Cloud Object Storage buckets
  • Use tools like rclone or OCI CLI for data transfer
  • Verify data integrity and consistency post-migration
4. Post-Migration Activities
  • Monitor performance and resolve any issues
  • Optimize Oracle Cloud configurations for cost and performance
  • Decommission AWS resources no longer needed
  • Document the migration process and lessons learned

Challenges and Solutions

  • Data Transfer Speed: Utilized parallel data transfer techniques to expedite the process.
  • Configuration Compatibility: Adjusted Kubernetes configurations to be compatible with OKE.
  • Downtime Management: Scheduled migrations during off-peak hours to minimize impact.

Results

  • Successful migration of Kubernetes workloads to Oracle OKE
  • Seamless transition of object storage from AWS S3 to Oracle Cloud Object Storage
  • Improved performance and reduced operational costs on Oracle Cloud
  • Increased team proficiency with Oracle Cloud tools and services
  • After completion of this of this project, we have observed drastic reduction in month on month billing against the AWS billing for same services.

Conclusion

The migration project from AWS to Oracle was a success, achieving all set objectives with minimal downtime and improved overall performance. The project highlights the importance of thorough planning, robust tools, and effective team collaboration.
